HEATER AND VENTILATOR FOR AUTOMOBILES AND OTHER VEHICLES.

Application filed February T0 at! whom it may concern:

Be it known that I, .Gnonon T. Miner, a citizen of the United States, resident of Seattle, in the county of King and State of Washin ton, have made a certain new and useful nvention in Heaters and Ventilators for Automobiles and Other Vehicles; and I declare the follovvin to be a full, clear, and exact description ov the same, such as will enable others skilled in the art to which it apfpertain's to make and use the invention, 1e erence'beinghad to the accompanying drawings, and to letters air-figures of reference marked thereon, which arm a part of this specification.

Figure 1 is a plan view of the frame of an automobile, equ pped with my invention.

I-Fi ure 2' is a side view of the heating cha n er. Figure 3 is a section taken on the line; H, Figure.

Figpre 4 is a front end view of the heating chain e1 *Figure :5 is a'detail fragmentary section taken onthe line 5 5 Fi ure4. The invention has relation to heating and ventilating means. for automobiles, power boats or other vehicles driven by an exp'losive engine or;by steam,-havin for an object to provide means for utilizing heat from'the exhaust from-the motor, and s cur rent of coldair set upbythe motion of the vehicle and drawn-from theuncontaminated air for'ward of the vehicle, for heating and ventilating purposes, and in such proportionsas may be desired."

' Theinventionconsists in the novel construction and combinations of parts, as hereinafterset,f01th'.'

In the accompanying drawings, illustrating an embodiment of the invention, the numeral 1 designates the floor of a motor car, in which is set a transverse heating duct or chamber 2, having its top'fiush' with said fioor and provided with an exit opening or openings 3 for the heated. air. Located below the horizontal duct2 is a supply chamher 4, surrounding the exhaustpipe fifrom the en ine and attached thereto at 5, the heat from 516 exhaust, radiated within the chamber 4, rising therein and being delivered at the top thereof to the transverse duct 2,

- through a passage of an upstandin extension 7 at one end of the supply ciamber. The passage 7 has a valve 8 controlling the same and adapted either to close the passage 13, 1323. Serial in. 618,878.

and uncovera dam .of the chamber 4, ending tothe outer air, or to open said passage and close the opening .9, the valve being also ada ted for adjustment topartially close sai assa e or said opening, to admit more or es s of the heated air to the duct .2 and to ermit more or less ofthe same to escapetot eouter air, as may be desired according to tlie'weather or other conditions to be met.

Connected also with the wardly thereof, is a cold air intake pipe 10, having one end 11 thereof extending well forward and screened and enlarged to take in uncontaminated air forwardly of the vehicle. Preferably a fan.27, supported upon intermediately pivoted arm 28, is adapted Jto be lowered into theend 11 of the air intake B1 c, a drive. belt-29 ,extendingfromthefan u to apulley .30 mounted 'upont-he opposite end of arm 28, whereby the ,belt is brought into contact with the radiator fan belt 31 whenever the fan Wis-brought into operating position. The fan is securedin or out of' operatingposition by means of adjusting arm .32,- andthe arm 28 is preferably made in section's'a-nd provided with a belttightening device 33.

A baffle plate or partition12 is provided between the exhaust- 'pipeand cold air intake pipe opening'to chamber 4, the latter-being preferably "below' the exhaust pipe and the afile plate placed horizontall therebetween and inclined slightly n war ly from front to rear, as is also t e bottom of said chamber.

'The cold air intake rear thereofwith a'branch 1'8 leadin to or communicating'with a' vertical cold air duct l4,the latter;at its upper .end communicating with chamber 2, avalve 15 being adapted either to close said branch 13 or to open the same and close the pipe 10. By adjustment of said valve the cold air maybe dolivered either at the bottom of the chamber 4, as may be requisite in cold weather, or

eropening 9 in the top 1 chamber 5%, forpipe. 10 is provided in I directly to the chamber 7, irrespectve of whether the valve 8 closes passage 7 or not, as would be desirable in warm weather, when the invention is desi ned to function for ventilating purposes. 61, in the latter case, the valve 8 may be partially openedto admit a regulated supply of warm air to the supply chamber.

In order to adjust the valve 8, any suitable means may be provided, as for instance an the link '19 bein moved, the valve will be adjusted; A co ed spring 20 is connected with therlink 19 and the tension thereof normally holds the-valve '8 in position to open the passage 7.- The' valve is also provided with suitable" means of operation,

as for instance an operating cord -21.

shown, the cords 16 and21 are connected to the lower ends of adjusting rods 25, lying along the steering post aud'mamtained in 'adj sted positio-n by spring 26.

he transverse heating duct or chamber 2 1s shown as provided in duplicate, as is s also the passage7, the-valve 8, the opening Qand'the vertical air duct 14, for use with automobiles-or v'eh-icles having more than one seat, and in such easesi a bafile plate. or partition"=22fis used'to act in con3nnotion with the bafiie plate 12,fo r betteradmixture of=the hot'and cold air.

For convenience in attachment npon the. exhaust pi e,' the supply chambers 13 preferably Ina e mtwo sections, i. e., up erand lower sections, having a meeting ine 23" and held togetherby removable fastening devices-24 The invention is; intended to take the monly place ofthe ineificient foot heaters so come used, and to provide a: convenient: means of heating without cost.

l'claimz j 1. 'In' means for heating motor vehicles, a
